Figure 4 is a block diagram of a recording and / or reproducing apparatus according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION Now, the reference will be made in detail to the present embodiments of the present invention, examples of which are illustrated in the attached drawings, wherein as reference numerals refers to the elements throughout the illustrations. The embodiments are described below for the purpose of explaining the present invention with reference to the figures. Referring to Figures 2 and 3, an information storage means in accordance with an embodiment of the present invention includes user data areas. C in which a user data is recorded and additional data areas D located before and after the user data areas C. The information storage medium may be a recordable storage medium or a means of storage. storage of reading information, only. Each of the user data area C contains a plurality of the user data 11 separated by one by a plurality of the first synchronization patterns -13. According to one aspect of the invention, the user data areas C include Error correction code (ECC) recording units. Each of the additional data areas D contains a plurality of additional data 21 separated by a plurality of the second synchronization patterns 23. Agui, as will be explained later, the first synchronization patterns 13 have modulation codes corresponding to the synchronization numbers shown in Tables 1 and 2 and are comprised of the predetermined combination of selected synchronization numbers. The second synchronization patterns 23 are comprised of predetermined types of patterns denoted by the reference numerals 23a and 23b in accordance with the same method as the plurality of the first synchronization patterns 13. In accordance with one aspect of the invention, the second Synchronization patterns 23 are different from the first synchronization patterns 13. In other words, the second synchronization patterns 23 are made up of patterns which are not used as the first synchronization patterns 13. For the conformation of the second synchronization patterns 23 to be different from the first synchronization patterns 13, a reproduction system such as that shown in Figure 4 can handle the additional data areas D because it has the ability to differentiate with certainty the additional data areas D, of the user data areas C. The number of the second synchronization patterns 23 depends on the length of the additional data areas D. It is preferred, but not a requirement, that the second synchronization patterns 23 be arranged at equal intervals for the purpose of increasing the effectiveness of the synchronization patterns. additional data from additional data areas D. In addition, additional data can be easily restored during playback. While not required, according to some aspect of the invention, the size of each plurality of user data 11 in the user data areas C is equal to the size of each plurality of additional data 21 in the areas of additional data D. This structure can be achieved "by adjusting the positions of the second synchronization patterns 23. It is preferred, but not required, that the total size of the additional data 21 in the additional data areas D be Integer multiples of the size di of the user data 11 recorded between / two adjacent first synchronization patterns 13a and 13b In other words, referring to Fig. 2, the size d2 of the additional data 21 recorded between two second synchronization patterns 23a and 23b is equal to the size di of the user data 11 recorded between the first synchronization patterns 13a, 13b, and the additional data 21 is recorded in two parts of ca gives one of the additional data areas D. Thus, the total size of the additional data 21 is an integer multiple of (for example, it is twice the size of) the size di of the user data 11. As a consequence of which the signals of synchronization are detected at regular intervals in all areas during the reproduction of the data, it is convenient to restore the synchronization signals. The structure of the information storage medium uses a limited run length (RLL) code (d, k) which will be described later. The RLL code indicates how many of the bits of value "0" are located between two bits of value "1". Thus, the code RLL (d, k) represents the minimum number of d and the maximum number of bits of value "0" between two bits of value "1", respectively. In the structure using the RLL code (d, k), the first synchronization patterns 13 generally include synchronization bodies that do not satisfy the RLL code (d, k) and synchronization identifications (IDs) that satisfy the RLL code (d , k). In other words, the synchronization bodies have a run length k + i when i is an integer which is greater than or equal to "1". The synchronization IDs contain different patterns to distinguish N different synchronization patterns. The second synchronization patterns 23 include the synchronization bodies that do not satisfy the code RLL (d, k) and the synchronization IDs that satisfy the code RLL (d, k). Here, the synchronization IDs contain different patterns to distinguish N different synchronization patterns. Figure 3 illustrates one embodiment of the data structure of an information storage medium that includes additional data areas D which have two additional data frames. The synchronization bodies and the IDs of the information storage medium having the above data structure are shown below in Tables 1 and 2. As can be seen in Table 1, an RLL code (1, 7) is used. . Each synchronization body has 18 bits, and each synchronization ID has 6 bits. The user data area C includes 9 user data frames for the synchronization data, and the additional data area D includes two user data frames for the synchronization data.
Table 1 As can be seen in table 2, an RLL code (2, 10) is used. Each synchronizer body has 22 bits, and each synchronizer ID has 10 bits. The user data area C includes 7 user data frames for the synchronization data, and the additional data area D includes 2 user data frames for the synchronization data.
Table 2 As shown in Tables 1 and 2 (the synchronization data in the additional data area D has different patterns compared to the synchronization data in user data area C. In other words, the synchronization IDs of the second patterns of synchronization 23 have synchronization patterns that are not used as the first synchronization patterns 13. Therefore, the additional data areas D can be handled and can be distinguished significantly from the user data areas C.
A method of recording information in and / or reproduction of information from an information storage medium having the structure described above will be described. As shown in Figure 2, the user data areas C that include basic ECC recording blocks and additional data areas D located before and / or after the user data areas are prepared in the information storage medium. C. Then, the second synchronization patterns 23 used in the additional data areas D are shaped differently from the first synchronization patterns 13 used in the user data areas C. Here, the second synchronization patterns 23 are plural and are arranged in equal intervals. It is preferred, but not required, that the second synchronization patterns 23 be arranged in the additional data areas D so that the size of each user data 11 in the user data areas C is equal to the size of each additional data 21 in the additional data areas D. The synchronization data in the additional data areas D contains synchronization bodies having second synchronization patterns that do not comply with the RLL (d, k) code and synchronization IDs that have second synchronization patterns that comply with the RLL code (d, k). The total size of the additional data 21 in the additional data areas D is an integer multiple of the size of the user data 11 recorded between two first synchronization patterns 13a and 13b. While specifically not limited, it is understood that the information storage medium may include CD-Rs, CD-RWs, DVD-RWs, DVD-RAs, DVD + RWs, as well as next-generation high-definition DVDs, such as Blu-ray discs, Advanced Optical discs (AODs) and other optical storage media to be developed not listed above. Figure 4 is a block diagram of a recording and / or reproducing apparatus according to an embodiment of the present invention. With reference to Figure 4, the recording and / or reproducing apparatus includes a recording / reading unit 1001, a controller 1002, and a memory 1003. The recording / reading unit 1001 records data on a disk 1000, which is an embodiment of a storage medium of the present invention, and reads the data from disk 1000. Controller 1002 records and reproduces user data 11 and additional data 21 in accordance with the present invention as set forth above in relation to to Figures 2 and 3.
As long as it is not required in all aspects, it is understood that the controller 1002 may be a computer that implements the method that uses a computer program encoded in a computer reading medium. The computer can be implemented as a chip that has a fixed program, or it can be a programmable computer with general or special purposes to execute the method. Additionally, it is understood that, in order to achieve the recording capacity of several dozen gigabytes, the recording / reading unit 1001 could include a low wavelength, a unit of the high numerical aperture type useful for recording dozens of gigabytes bits of data on disk 1000. Examples of such units include those units that use light with a wavelength of 405 nm and have numerical apertures of 0.85, those units compatible with Blu-ray discs, and / or those units compatible with Advanced Optical Discs (AOD), but is not limited to these examples. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the present invention. as defined by the following claims and equivalents thereof.
INDUSTRIAL APPLICABILITY As described above, an information storage means and a method of recording information thereon and / or reproducing information thereof in accordance with the present invention can be consistently maintained with the formats of different types of storage media of recordable information and has playback compatibility in a disk drive. Also, since the synchronization patterns used in the user data areas may conform differently to the synchronization patterns used in the additional data areas, the additional data areas may be additionally efficiently separated from the data areas of the data. user . In addition, by uniformly maintaining the length of the recorded data in the user data areas and the additional data areas, synchronization signals can be detected at regular intervals in all areas during the reproduction of the data. Thus, it is convenient to restore the synchronization signals.
